RAM opinion needed

So I have decided to go with a FX 6300 build,and I'm pretty sure I will go with the Asus M5A99FX PRO R2.0 motherboard.I will go with 2x4GB  CL9 1600Mhz  Kingston RAM
 

      I'm not quite sure should I go with a  1.65V or 1.5V or 1.35V      

                                                I'm thinking the 1.35V option is the best one ??              

Yes the 1.35V would be the best and you could probaly overclock it to 2133Mhz if it's 1600 at stock. Also please move this to the Other Hardware section.
